+
+## Model description
+
+This model is a Candidate Set Generator in **"CDGP: Automatic Cloze Distractor Generation based on Pre-trained Language Model", Findings of EMNLP 2022**.
+
+Its input are stem and answer, and output is candidate set of distractors. It is fine-tuned by [**CLOTH**](https://www.cs.cmu.edu/~glai1/data/cloth/) dataset based on [**facebook/bart-base**](https://huggingface.co/facebook/bart-base) model.
+
+For more details, you can see our **paper** or [**GitHub**](https://github.com/AndyChiangSH/CDGP).
+
+## How to use?
+
+1. Download the model by hugging face transformers.
+```python
+from transformers import BartTokenizer, BartForConditionalGeneration, pipeline
+
+tokenizer = BartTokenizer.from_pretrained("AndyChiang/cdgp-csg-bart-cloth")
+csg_model = BartForConditionalGeneration.from_pretrained("AndyChiang/cdgp-csg-bart-cloth")
+```
+
+2. Create a unmasker.
+```python
+unmasker = pipeline("fill-mask", tokenizer=tokenizer, model=csg_model, top_k=10)
+```
+
+3. Use the unmasker to generate the candidate set of distractors.
+```python
+sent = "I feel <mask> now. </s> happy"
+cs = unmasker(sent)
+print(cs)
+```
+
+## Dataset
+
+This model is fine-tuned by [CLOTH](https://www.cs.cmu.edu/~glai1/data/cloth/) dataset, which is a collection of nearly 100,000 cloze questions from middle school and high school English exams. The detail of CLOTH dataset is shown below.
+
+| Number of questions | Train | Valid | Test  |
+| ------------------- | ----- | ----- | ----- |
+| **Middle school**   | 22056 | 3273  | 3198  |
+| **High school**     | 54794 | 7794  | 8318  |
+| **Total**           | 76850 | 11067 | 11516 |
+
+You can also use the [dataset](https://huggingface.co/datasets/AndyChiang/cloth) we have already cleaned.
+
+## Training
+
+We use a special way to fine-tune model, which is called **"Answer-Relating Fine-Tune"**. More detail is in our paper.
